Chris Brown Arrested After Woman Claims He Threatened Her With Gun

R&B singer Chris Brown was arrested Tuesday after a woman claimed he threatened her with a gun, Los Angeles police said hours after officers arrived at the entertainer's Los Angeles mansion and returned with a search warrant.

"Mr. Brown is going to be transported where he will be arrested for ADW — assault with a deadly weapon," LAPD Lt. Chris Ramirez told reporters at around 5 p.m. local time (8 p.m. ET). Brown will be formerly booked sometime Tuesday night or early Wednesday morning, police said.

The unidentified woman reported the early-morning incident to police, saying 27-year-old Brown pointed the gun at her before she left his gated estate in the wealthy Los Angeles enclave of Tarzana, law enforcement sources told NBC News.

The LAPD received a call at about 3 a.m. and sent several patrol cars to the home later Tuesday morning.

People were being removed from the residence and would be interviewed following a "protective sweep" of the home, Ramirez said earlier.

"The investigation is still ongoing, the search warrant is s still being conducted and evidence is still being collected," Ramirez said Tuesday afternoon. Ramirez said he couldn't comment on whether any weapons were found at the home because the search was ongoing.

Brown, who has previously pleaded guilty to a felony assault, had refused to come out of his home and talk with officers. Sources earlier told NBC News that other witnesses have also been uncooperative.

The "Run It!" singer recorded a profanity-laced rant on his official Instagram account Tuesday morning, saying he was fed up with police at his home.

"Every three months, y'all come up with something, bro. What is it? What's going to be next?" he asked, adding, "At the same time, when I call police for stalker people … they don't come until the next day."

Ramirez said Brown was later cooperative with detectives. Brown's attorney, Mark Geragos, did not immediately return calls for comment but was seen arriving at the home after noon.

Police were told they needed a warrant to enter the property. The LAPD's Robbery-Homicide Division, which in addition to high profile and complex murders and robberies also handles cases involving VIPs and celebrities, is investigating the case.

The Grammy-winning artist has been a lighting rod for trouble. His most notable arrest took place in 2009 for assaulting then-girlfriend Rihanna following a pre-Grammy party.

He pleaded guilty to felony assault and was sentenced that year to five years' probation, a year-long domestic violence class and six months of community labor. He had issues complying with the terms of probation in that case, but completed that probation in Los Angeles County early last year.

Since then, he has also dealt with a fraud complaint against him in the Philippines last summer for allegedly canceling a New Year's Eve concert and was the subject of a potential battery investigation against a model in Las Vegas in January. She claimed that he hit her and took her cellphone, but police never pursued charges.

Brown moved to Tarzana about a year ago, and the LAPD has responded multiple times to the location, including for a home invasion robbery and for a report that Brown and others were illegally riding ATVs on a neighbor's property.

He bought the more than 8,300 square feet of living space for $4.35 million, and it included a security system with 16 cameras, The Los Angeles Times reported last summer.

On Tuesday morning, one of Brown's neighbors, television and radio host Jillian Barberie, tweeted the noise from helicopters as they flew over the area.
